Day-14 | Configuration Management With Ansible |Puppet vs Ansible |Live Projects |  

At first system administrator used to do upgrades, secure patches and installation on 100s of servers using shell script that had to loop over all 100s of servers. With cloud( micro service architecture) no. of servers increased and the compute/resources had decreased. Earlier we had to take care of distribution of OS(alpine, ubuntu), so the script might not work. To solve this configuration management came into picture. Puppet, chef and Ansible . Why Ansible over others? Ansible is much a push mechanism model. Write Ansible script at one instance and update all the worker nodes. Ansible is agentless, just put DNS or ip adress of servers in inventory file and have ssh password-less authentication configured, along with python3 installed by default in Linux distros. 2. Ansible also has feature of dynamic inventory. If you are creating 100s of servers in AWS cloud, Ansible will automatically detect new server. 3. Support both Windows, AIX and Linux all distros 4. Ansible is pretty simple, uses simple yaml manifest.

Your efforts towards helping devops community is incredible

Just for you anna, I have never skipped even a single ad in your channel even if it's for >5 mins :)

Explanation was crisp and clear , easy to understand the concepts. Hands off for your efforts in explaining devops concepts in a simpler way.👏

The sessions are going really nice, it's really helpful, thank you❤🙏

Congratulations Sir Keep Rocking

You are best in teaching the things in crystal manner. Want to know how to write the yaml scripts.If possible make a video on this.❤

Excellently explained

So nice Abhi. Thank you😊

Thanks alot Abhishek bhaiya 😇

i completed this video abhishek

u earned new subscriber + a big fan 😀

Keep rock it Abhishek bro

Excellent Sessions and appreciate abhishek only small suggestion: Can we cover industry-specific real time use cases? I know its very difficult but you are gem person.

Videos are very helpful....thank you so much. Please provide some videos on how to create API endpoint using Terraform

Day-14 done ✅

Doing a speed run on your devops/ aws videos before I start my application. If I get a job you’re the reason xD

Thank you very awesome session

You are the best 💕💕

excellent explanation ,very much clear on this

Great Explanation, Abhishek. Also please discuss the Ansible Tower AWX.

Great sir 👍🏻.. well explained

awesome explaination sir

great bro you have done great work.😍

Exited for tomorrow's video 🤩

Perfect video

Loved this session

I paid 18k for this course but your course is far more better than that one. My name is Murthy. How can I contact you for any advanced level courses? Hope you will reply.

BEST😊

Sir, please let me know if Iam right...? Ansible uses python for it's modules and YAML for writing playbooks?

All sessions are having really good explanations. In this session can you please elaborate on what are microservices, and how they are used?

Hi Abhishek, I have a question regarding the interview questions you provided. In one of the questions, you mentioned that the programming language used in Ansible is Python, but you also mentioned YAML for the same question later. Could you please clarify this?

Hi Abhishek, Thanks for the video, can you try one video for Ansible Tower with simple? if possible.

Gold content

The tutorial was very great👏 Would love to watch a video on just ansible roles. I have a question - How we are supposed to enable password authentication if we've 100s of servers. I got one answer on the internet using boto3 module. Is there any other method❓

Thanks 😀

thank you

hello Abhishek, can you briefly explain the difference between Ansible playbooks and roles? How would you organize your Ansible project to ensure modularity and reusability of code?

Thanks bhau♥

nice explanation.

perfect!!

Great video, thanks you 👍

Thank you ^^

Thanks sir

very good session

Thank You Sir!

Abhishek you said in int questions 1) ansible uses python & 5) ansible programming language YAML. little confused here can you explain in shot.

Hi, can you please make a video & explain step by step the writing/structure of Ansible & Terraform in a simple manner & in layman's terms, like when & where to add spaces, hyphens, what is variable, etc it's a bit confusing ...I am not from a programming background hence find it difficult to understand the structure of writing Ansible & Terraform. Please it's a request, do reply

Greta Video

Additional features are dynamic addition of servers using dynamic inventory, idempotency and conditional execution.

Thank you ❤

Can you help me with difference between ansible and Jenkins and which tool should I learn first or is it necessary to learn both tools?

Bro can you pls do an one dedicated zero to hero ansible video It's helpful alot My self iam slow learner this video is little faster My req can you pls do an one dedicated ansible video

10/10

i've got little confusion here...( which language do we use in Ansible..!!!) python is to wright custom modules, yaml is to wright Ansible playbooks....am i correct...?

Hi Abhishek, The programming language Ansible uses to write modules is Python, and the programming language it uses to write automation tasks is YAML. Did I understand this right? There is slight confusion here

excellent work but is some one please help to get the command which to used over lab setup

Thanks for sharing excellent videos .Any ways to join your online Devops training sessions .

For windows Ansible uses winrm protocol, for linux it's ssh

bro you expalined push model in ansible but missed pull in puppet

You can write your own ansible module for installing load balancer for your own organisation in python. You can share them using Ansible galaxy so other team can utilize. Ansible galaxy acts as bridge. Sharing is always possible, give back to community and take benefits from community.

Thnx sir

What are the dependencies that ansible is needed? This is also one of the interview question in which the interviewer was asked in my interview . Can u answer this ? And also which version of ansible that currently used in your IaC environment?

Does Ansible support all cloud providers like AWS,azure,gcp.. Ans. For Ansible it doesn't matter what your cloud provider is. You only need public ip adress, is ssh access allowed publically to your machine(laptop).

can i swich to ur zero to hero ansible playlist from here or should i continue here only ... plzz reply

Hi Abhishek, Openings on ansible tower role will be good in market?

@Abhishek.Veeramalla Should I watch Ansible zero to hero after completing this roadmap or should I start watching after this video

In AWS while creating EC2 instances - we can give some configurations right? So using ECS which has cluster of EC2 instances or something, can't we do the configurations?? Should Ansible be used? Also in Puppet when you are giving multiple slaves - so if 1000 machines are added. you go and add all the 1000 again in the master file?

Hello Abhishek thanks for the video I have one doubt about ansible What is the global fact ? It's like an global system variables or any else.

Sir you have said that ansible is push mechanism like we can write our own notebook and push ..wt abt puppet pull mechanism?

Bro, do you have any videos on Ansible molecule?

Hello Abhishek, Is it enough to watch these 2 videos for learning ansible ?

hello abhishek ,i understood push based ,but what is pull based .explain

Notes of this video- Scenario- System admin has to configure 100s of servers, each with different OS like Ubuntu, CentOS, Windows. Tasks include updating OS, security patches, default installations like git, databases on servers. Issue- Doing this manually on every server is difficult. Hence, scripts were used. Powershell scripts for windows machines, other shells for Linux machines. Even in Linux machines, scripts varied based Linux flavours and type of script (bash, zsh, tsh, etc). This script will then loop over all servers to perform configuration tasks. With cloud and micro service architecture adoption, number of servers have increased further. Hence, even scripting approach is not very efficient. This led to concept of configuration management. Various tools are used for configuration management. Puppet and Chef were pioneering tools while Ansible, developed by Red Had is most popular. Why Ansible over Puppet? 1. Puppet = Pull mechanism, Ansible= Push mechanism. Eg. Managing 10 EC2- Write ansible playbook and push to all 10 EC2 2. Puppet uses Master-Agent architecture- Have to create Master server and configure all 10 EC2 as agents. Ansible is agentless. Write only ip/dns of machine in inventory file and have passwordless authentication enabled. In case of dynamic demand, auto-scaling is possible by changing inventory file. Even better- 'Dynamic Inventory' feature auto detects demand- doing away need to change inventory file. 3. Support for Windows is better in Ansible than Puppet 4. Ansible Playbook is written in YAML which is widely used. Puppet configuration is written in Puppet language. Issues with Ansible 1. Support for Windows is still not seamless 2. Debugging is not easy. Can run ansible in debug mode but debugging logs are not easy to understand. 3. Performance issues- when managing thousands of servers Enjoy!

hello abhishek sir, just asking this question as red hat is one of my dream company so can you please let me know how much a fresher should be technically sounded to be eligible for junior role at RH.

i have a question mate i learn jenkin from 1 person in my country she said in the world currently , some of the company dont use ssh like ansible because of security of protocol ssh is not best practice could you explain why :
